Debugging

When debugging your code, you can use more than just console.log or attaching the node process to a debugger. Another option is to use ctx.state.json to provide a custom object for debugging.

Using ctx.state.json

To pass a custom object to ctx.state.json for debugging, follow these steps:

1. Create your custom object.
2. Assign your object to ctx.state.json.
3. Access the corresponding route + .debug.json to view your object. For example, if you want to debug the route /furstar/characters/:lang?, you can access the URL: /furstar/characters/en.debug.json

Here's an example of how to use ctx.state.json taken from furstar/index.js

const info = utils.fetchAllCharacters(res.data, base);

ctx.state.json = {
    info,
};

In the example above, we're passing the info object to ctx.state.json, which we can then access using the corresponding route + .debug.json.
